RE: [microblaze-uclinux] User application debug.

["Leonid" <Leonid@xxxxxxxxx>]

I managed to fix the problem by leaving in EDK design only caches among
Microblaze core features - some other available features don't work well
on Spartan-2e.

You can debug busybox like any other application, just invoke busybox
itself with the applet name as the first param.  e.g.


# gdbserver host:1234 /bin/busybox ls /bin/*

If you are unable to get a busybox shell, then prehaps try one of the
other shells (user/vendor settings -> core settings), and set it to be
/bin/sh.  Still build the busybox shell, but your system should boot
into the alternative first.  Then debug as above.

Regards,

John
